LYRICS
You change your mind like a girl changes clothes
Yeah, you PMS like a chic I would know
And you over-think always speak cryptically
I should know that you're no good for me

CHORUS
'Cause you're hot then you're cold
You're "Yes" then you're "No"
You're in then you're out
You're up then you're down
You're wrong when it's right
It's black and it's white
We fight, we break up
We kiss, we make up
You don't really wanna stay, no
But you don't really wanna go
You're hot then you're cold
You're "Yes" then you're "No"
You're in then you're out
You're up then you're down

We used to be just like twins so in sync

The same energy now's a dead battery
Used to laugh 'bout nothing, now you're plain boring
I should know that you're not gonna change

Someone call the doctor
Got a case of a love bipolar
Stuck on a roller coaster
Can't get off this ride

You change your mind
Like a girl changes clothes

CHORUS X2

You don't really wanna stay, no
But you don't really wanna go
You're hot then you're cold
You're "Yes" then you're "No"
You're in then you're out
You're up then you're down, down
